14857089 ÷ 210 
Let's see how many times 210 fits into 14857089.

Let's proceed to step 1:
1 divided by 210 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 210

On to step 2:
14 divided by 210 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 210

Let's proceed to step 3:
210 goes into 148 0 times with a remainder of 148.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 148 to get 148.
Take the next digit (5) from the dividend and append it to 148, then repeat: 1485 / 210

On to step 4:
When dividing 1485 by 210, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 1470 from 1485 to get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 210

On to step 5:
210 goes into 157 0 times with a remainder of 157.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we subtract 0 from 157, we get 157.
Bring next digit (0) of the dividend behind the 157 and repeat the process: 1570 / 210

On to step 6:
When dividing 1570 by 210, we get 7 with a remainder of 100.
Use 7 as the next digit of our solution. 
Result so far: 707.0
Subtracting 1470 from 1570 leaves us with 100.
Grab the next digit (8) from the dividend, add it to 100, then carry on: 1008 / 210

On to step 7:
210 can be fit into 1008 4 times, resulting in a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 7074.0
If we take 840 away from 1008, we end up with 168.
Append the next digit (9) from the dividend to 168 and continue with: 1689 / 210

Let's proceed to step 8:
If we divide 1689 by 210, we get 8 and a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 70748.0
If we take 1680 away from 1689, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
90 divided by 210 is 0 with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 70748.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
900 divided by 210 is 4 with a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 70748.04
Deduct 840 from 900 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
210 can be fit into 600 2 times, resulting in a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 70748.042
Subtracting 420 from 600 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 12:
The number 210 fits into 1800 8 times, leaving a remainder of 120.
Put 8 as the next digit of the answer. 
Result so far: 70748.0428
Deduct 1680 from 1800 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 13:
If we divide 1200 by 210, we get 5 and a remainder of 150.
The next digit of our result is 5. 
Result so far: 70748.04285
Deduct 1050 from 1200 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 14:
210 goes into 1500 7 times with a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 70748.042857
Subtract 1470 from 1500 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 15:
The number 210 fits into 300 1 times, leaving a remainder of 90.
Record the quotient 1 as the next digit in the result. 
Result so far: 70748.0428571
Deduct 210 from 300 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 16:
900 divided by 210 is 4 with a remainder of 60.
The next digit of our result is 4. 
Result so far: 70748.04285714
If we subtract 840 from 900, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 70748.04285714 with a remainder of 6e-08.
